以天津市地铁11号线某地铁站点为例，进行基坑降水水资源论证分析。项目总占地面积12 230 m2，车站主体为地下三层岛式站台，主体基坑降水面积3 938 m2；车站设2个地下2层风道和2个出入口，附属基坑降水面积2 480.5 m2。在收集建设项目支护、止水、降水井设计方案的基础上，进行了基坑降水量计算，并分析了降水对周边环境及用水户的影响。
Abstract：Taking a subway station on Tianjin Metro Line 11 as a case study, the water resources demonstration and analysis for foundation pit dewatering were conducted. The project covers a total area of 12,230 m2, with the main station being an underground three-level island platform and a main foundation pit dewatering area of 3,938 m2. The station includes two underground two-level air ducts and two entrances/exits, with an auxiliary foundation pit dewatering area of 2,480.5 m2. Based on the collected design schemes for support, water-stopping, and dewatering wells, the dewatering volume of the foundation pit was calculated, and the impact of dewatering on the surrounding environment and water users was analyzed.
